ABAP Function for Material Unit of measure check

Hi Gurus,

i need to find a FM, a sequence of FM or anything else that return the same list (in internal tables whould be great!) like when i try to change the UM on a material but there are some open items and i got "DISPLAY ERRORS".

i need this because using BAPI_MATERIAL_SAVEREPLICA i got only the message "The base unit of measure cannot be changed; choose "Display errors".
